摘要： This magnetic recording device is provided with a magnetic write head having a magnetic pole, and a magnetic recording medium having a plurality of data recording blocks. Each of the data recording blocks is formed with a plurality of write tracks, and separated, in a write track width direction, from neighboring one of the data recording blocks with a writing exudation suppression section in between. With this configuration, a magnetic mutual interference of the adjacent data recording blocks at the time of a data rewriting process is avoided even when a mutual interval of the data recording blocks is narrowed, and a good recording state is maintained in each of the data recording blocks. Therefore, it is possible to achieve an improvement in a recording density, while realizing the good and brief data rewriting process for each of the data recording blocks.

摘要： In the head slider of the present invention, recording and reproducing electrode pads and heater electrode pads are attached to the same surface of an overcoat layer. The heater electrode pads are located on both sides of a group constituted by the recording and reproducing electrode pads. As a consequence, leads for the heater are located between respective leads for recording and reproducing head parts, whereby crosstalk can be prevented from occurring between the leads for the recording and reproducing head parts.

摘要： The heaters in the respective thin-film magnetic head in the bar are electrically connected to its neighbors, and a variable resistor is connected to each of the heaters in parallel. The resistance of each of the variable resistors is varied depending on the amount that the medium-opposing surface (ABS) of the thin-film magnetic head is to project. Also, the medium-opposing surface of the thin-film magnetic head in the magnetic head bar is polished while energizing all the heaters by the same power supply.
